Speex dev - Aug 2008 - Echo Cancellation, what format does the .sw files have

Hi

I'm debugging why echo cancellation does not work in my app using the
DUMP_ECHO_CANCEL_DATA flag.

What format does the data I receive have, looks like 16bit integers just dumped
but when plotting it in MATLAB I do not get a raw audio data signal I expected.

 

Kind Regards

//Gunnar

The files are simply signed shorts (16-bit) in the same endianness as
the machine on which they were produced.
